在一些中小型制冷装置中,常见两台(或几台)压缩冷凝机组(不带专用贮液器,冷凝器为冷凝贮液器)并联的设计方式,见附图1。这种设计中,即使在机组之间加设了汽相均压管,仍会出现一台机组工作另一台不工作时两个冷凝贮液器之间液面不平衡的现象,使工作机组中液面低于停机机组中的液面。在液量不太多的系统中,将出现停机机组中存有液体而工作机组中冷凝贮液器的“液封”消除、高压
In some small and medium-sized refrigeration installations, the common design of two (or more) condensing units (without dedicated reservoirs and condensers with condensate reservoirs) in parallel is shown in FIG. In this design, even if the vapor phase pressure equalizing pipe is additionally installed between the units, the liquid level imbalance between the two condensate reservoirs will still occur when one unit is working and the other is not working, The liquid level is lower than the level in the shutdown unit. In systems where the fluid volume is not too high, there will be a “liquid seal” elimination of the condensate reservoir in the shut-down unit and the high pressure
